IMPROVED MEDICAL COMPOUND.

- Specification forming part of Letters Patent No. 64,611, dated May 7,1867.

To all whom it may concern:

Be it known that I, JAMES A. WILLIS, of Cherry Valley, Otsego county,New York, haveinvented a new and Improved Medical Compound; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same.

The present invention relates to an improved medical or chemicalcompound for the removing and curing of bony substances in horses, suchas ring-bones, spavins, splints, &c.

This compound is composed of the following ingredients, mixed together,and in about the proportions and in the manner below stated: four ouncesquicksilver, two ounces nitric acid,

two drams cantharides, and two ounces sulphuric acid.

The above ingredients are mixed together in a stoneware pot, partiallyimmersed in cold water, to serve as a condenser, by first putting in thequicksilver, then the nitric acid, then the-oantharides, andthen thesulphuric acid, in small quantities or amounts at a time, stirringbriskly with a wooden paddle to prevent it from boiling over; when, itbeing nearly cold, add one ounce of sesqui-carbonate of ammonia,pulverized; when, allowing the compound to become cold, it is ready andfit for use, as will be hereinafter explained.

In addition to the above compound, I also produce or make a compoundfrom two ounces of olive-oil, one-half ounce of magnesia alba, and oneounce of aqua ammonia, by mixing the whole together in a porcelainmortar.

In using the compound above described, first cut the hair over theenlargement close to the skin, when apply the compound just describedwith a small wooden paddle, once at least a day, very thoroughly,spreading it over the enlargement until removed, when it will feelspongy or soft, with a serous fluid oozing through the skin. Thecompound on the enlargement is then to be cleaned off, when, applyingthe compound lastly or secondly described, rub it in until all theforeign heat is removed.

, By the application of the first-described compound, the bony substanceis dissolved, or, in other words, the earthy salts are separated fromthegelatine, when, by the second compound, the first is neutralized, andany deteriorating or destructive efiects to the natural bones prevented.

I claim as new and desire to secure by Letters Patent- The medicalcompounds, substantially as and for the purposes described.

The above specification of my invention signed by me this 22d day ofFebruary, 1867.

JAMES A. WILLIS.
